Carrier 48HJF012 Control Board
The control board is constructed to direct everything including the gas valve, the ignition igniter, all the sensors and the blower all at once. Heating and cooling systems will not even operate whatsoever without the board properly connected to the unit. The board you select is supposed to have a part number that matches the brand and the model of the system you have installed. It is of utmost importance upon picking a replacement board due to the vast differences in heating and cooling systems.
